As mentioned above, in the technique of applying an epoxy compound to polyester fibers and subsequently heat-treating them, the epoxy compound adheres to the surface of the heating roller used for the heat treatment, and the resin of the EVO 4 copolymer is deposited on the surface of the heating roller. A film is formed. When polyester fibers are wound around the heated L-1-la on which this resin film has been formed and subjected to hot stretching or heat treatment, the heating [1-la] changes the frictional resistance between the polyester fiber and the polyester fibers. The thermal conductivity of the polyester fiber changes, and the physical properties of the polyester fiber, especially its strength, elongation, and adhesion to rubber, change by 1! This method has the disadvantage that the frequency of cutting of the entire thread increases. Furthermore, if it becomes clear that a resin film has formed on the surface of the heating roller, resulting in a decrease in thermal conductivity, the work of replacing the heating roller will have to be canceled, and operations will have to be interrupted during this period, resulting in poor operability. However, it has the drawbacks of lowering the temperature and requiring work to remove the resin film.
